WheelUpDown - GetKeyState, A_EventInfo

Alternative, pass the wheel delta as parameter to the hotkey callback. Then you couldn't use a label if you wanted the wheel delta ofc. Or, just rename A_EventInfo to A_WheelDelta. (I prefer the first)
WheelUp is not a key or button and doesn't have any state, so what are you expecting
I'd expect an exception, since it should be considered invalid input for the reasons in the quote. Maybe there are other reasons it shouldn't?

Hotkey callbacks currently do not receive parameters because hotkeys are typically written directly, and cannot receive parameters. One can write a function hotkey, but it is more verbose and requires assigning a unique name to the hotkey. Once parameters come into play, I suppose that we must consider other potential parameters (such as those that have meaning to all hotkeys).

The nature of my question was more along the lines of "why would anyone care what this does" or "why are you even passing this value in the first place", and was asked to the OP in the context of v1.
